PULVERIZING ATTACHMENT FOR PLOWS.

Application filed March 18, 1927. Serial No. 176,390.

This invention relates to pulverizing' attachments for plows and moreparticularly to a device so mounted on the plow that it will engage thefurrow slice in the rear of the mold board and break the same into smallpieces.

One object of the invention is to provide such a devicewhich may bemounted on the beam and supported independently of the mold board; andwhich will be of a strong durable character.

A furthcr object of the invention is to proide such a device which maybe so adjusted with relation to the beam as to support the pulverizingelement in the desired position,

A further object of the invention ls to pro-' vide in such adevice apulverizing element the parts of which will be adjustable relatively oneto the other and which will be adjustable as a whole with relation tothe supporting member.

Other objects of the invention will appear as the device is described indetail.

In the accompanying drawings Fig.1 is a front elevation ofa portion ofaplowshowing my invention applied thereto; Fig. 2 is a side elevation ofa device embodying my invention; F ig. 3 is a top plan view of the same;Fig. 4 is an elevation of the supporting frame of the pulverizingelement; and Figs. 5 and 6 are detail views of this supporting frame.

In these drawings I have illustrated one embodiment of my invention butit will be understood that this particular embodiment has been chosenfor the purpose of illustration only and that the apparatus may takevarious forms without departing from the spirit of the invention.

In the particular construction here illustrated the apparatus comprisesa pulveri'zing element indicated as a whole by thereference numeral 10.This pulverizing element comprises a plurality of pulverizing fingers orsoil engaging bars, 11, in the present instance three, which are rigidlysecured to a supporting frame 12 which is arranged in an uprightposition so that the pulverizing fingers will be supported one above theother and spaced apart. The supporti ng frame 12 may be of any suitableconstructi on, and may either be cast or be formed from sheet metal. Theparticular supporting frame here illustrated is formed from sheet metaland to facilitate the manufacture thereof, as well as to provideadditional adjustments, it is formed in two parts. One of thesesupporting frame, 15, r y Y shaped and has parts or bracketsltlextendpartsj 13, is substantially structionand'has' laterally extendingportions 'or brackets 14 extending in the same direction therefrom andsubstantially parallel one with the other. The other part of the ingtherefrom in opposite directions. One, of these brackets 16 extendssubstantiallyparallel with the adjacent bracket 14 of the other a partof the frame and is rigidly secured therewhole comprises a to so thatthe frame as a rigid structure. The pulverizing bars 11: are secured tothe laterally extending portions or brackets 14 and 16 of the frame andbecause of the arrangement of these bracketswith re- U shaped in conissubstantially Z;

lation one to the other the pulverizing bars 1 will be out of verticalahnement. Preferably the pulverizing bars are adjustable with relationto the frame to enable them to be positionedqat different angles withrelation thereto and, further, the bars are adjustable with relation oneto' the other so that they may, if desired, be caused to extend atdifferent angles. The character of the adjustable connections betweenthe frame and the pulverizing bars may take various forms and Will in ameasure depend upon the eharacterof the frame. In the present instance,where the frame is of the sheet metal construction above described,the'supporting portions or. brackets 14.- and 16 of the frame areprovided with arcuate slots 17 throughwhich extend the bolts 18 by meansof which the bars-are secured to the brackets. The bars are supported onthe outer surfaces of the brackets so that they will have a relativelywide range of adjustment with relation thereto. Preferably theintermediate pulverizin" bar 11 is supported between the ad acentrackets14 and 16 of the two parts of the frame and the bolts 18 which connect.this bar with the brackets also serves to connect the two parts of theframe one to the other.-

The pulverizing element 10 is carried by a supporting member or bar 19,the rear end of which is rigidly secured to the frame 12 and the forwardend of which is provided with means for attaching the same to the beam20 of the plow. As here shown, this attaching means is in the form of abracket 21 rigidly secured to the beam and preferably this bracket is inthe form of a clamp to engage the beam so thatit may besecured theretowithout forming holes in the beam or otherwise weakening the same andmay be Securedfoth'e beam in different positions. lhe supporting bar issomounted on the bracket that it will extend rearwardly therefromadjacent to the upper edge of the mold boardQQ of the plow and willsupport the pulverizing element behind this mold board with the fingersprojecting inwardly beyond the same at such an angle thereto that theywill engage the furrow slice which is turned over the mold board. Theconnection between the supporting member '19 and the bracket 21 ispreferably apivota'lone so that the pulverizingelemen't may be movedtoward or from the "mold board. As here shown, the bracket 21 extendssome distance to the rear of the beam and is "provided with a bearing 23which, in

V the present instance, comprises 'a-cliprigidly secured to the bracket.This bearing is .ar-

ranged at an inclination to the vertical and has mounted therein a rod24. The'upper end of this rod projects some distance above the bracketandth-e forward end of the connect- 'ing bar 1 9 is pivotallym'ountedthereon, prof erably by means of a bolt 25 extending throughthebar and through the rod. In

' the present instance, a reinforcing"member or strapQG-is securedtoth-e supporting'bar and overlaps the upper portion at the rod to receivethzft end ofthe bolt 25 opposite the bar 19 and thus provide a firmsupport for the bolt yor pivot pin. The lower en'dof the red ban-isconnected to theconnecting rod.

tiorr to the-connecting bar. onezpart of the supportingframe, the part13,

24 extends below the bracket 21 'and'a brace bar27 is'eonnected atone'end \VIth'the lower portion of the rod and at the other'end with theconnecting bar 19. Theconnection be- I tween the brace bar 27 andconnecting bar l9 is an ustable one so that the'connecting bar'andipulverizmg element may be vertically ad usted. Ashore showmtheconnecting bar has a series of openings .28 each adapted to receive abolt 29 bymeans of which the brace By attaching-the brace bar totlreconnecting bar at'dilferent points the vertical position of theconnecting bar may be changed. The rear end of'the connecting bar 19maybe secured to the pulverizing element in any suitable -n1a-nner butthe connection is preferably an "adjustable one so that the supportinglirame 12 may extend at different angles with relai is here shown,

is provided in its vertical portion with arcuate -slots"'3'0 to receivethe bolts 31 by means of which the connecting bar is secured to thesupporting frame. The'pulverizmgelement is preferably connected "withthe plow beam by a draft devicewh-ich is separate from the supportingmember '19. As here shown the frame 12 of the I u 7 i xpulverizingelement has secured thereto a lug -'o1"bracket 32, which may be attachedto the framebythe bolts 31 by means of which the "supporting bar '19 isconnected therewith.

Extendingjthrough this bracket 32 is a short different links with th "rbracket 21 has a rearwardlyand H WQI'CllY.

extending arm '35 which is rigidly secured thereto and whiclrhas in itsrear end an opening to receive one of the links of the chain 3%, asshown at A pin 37' extends through the link and scrves to lock the samein'the opening in the arm The length of the draft device may be variedby connecting tll1135. The pin 8'? is of such a character 'tnatit willsupport the normal strains to which the pnlverizing element is subjectedbut will yield or be sheared oil when the pulverizing element issubjected to, abnormal strains, as when it strikes a stone or othercbstruction through which it cannot pass. thus ,1 sing the draft deviceand permitting the pulverizing element to move a '21. from the moldboard and pass the obstruction without causing injury to other parts oftheapparatus.

The operation of the apparatus will be readily understood fromtheforegoing description of the several partsthereo'f and it will beapparent that I have provided a device of such a character that thepulverizing fingers will engage the furrow slice immediately in the rearof the mold board and will pulverize the same, that is, will break thesame intorelatively small pieces. The extent of the pulveriza'tion orthe breaking up of the furrow slice will depend, or course, in ameasure, on the cha actor and condition "of the soil. 7 The pulverizingelement and its supporting draft 'devicesare of such a character thatthe soilengaging bars may be arrangedin a position most suitable for"the particular plow or the particular soil with which the deviceisfbeing used. The device as a whole isisimple in its construction andof such a character that it can be manufactured at a relatively lowcost.

Vfhile I have shown and described one embodiment-of my invention I wishit to be understood that 1 do not desire vto be limited to the detailsthereof as various modifications may occur to a person skilled in theart.
